Built for MiSTer FPGA

Organize. Track. Compete.

Collection Management

Organize your entire arcade library with smart detection and rich metadata

Smart Game Detection

Visual Game Identification

Every game in the database is identified by its authentic gameplay screenshot. Browse your collection visually and instantly recognize any title without reading a single name.
